Top 5 stacking battery companies in the world
In the three different forms of lithium batteries, the cylindrical battery only uses the winding process, the flexible packaging process only uses the lamination process, and the square battery can use either the winding process or the lamination process. At present, the future product planning of power battery companies in the world is gradually switching to stacking batteries.
Each battery manufacturer proposes a differentiated solution for square battery, such as BYD’s blade battery and SVOLT’s short blade battery. BYD blade batteries have been mass produced in a large scale, and the annual output of the four major bases is expected to reach 85 Gwh.
On November 2, 2022, SVOLT announced the successful mass production of the third-generation high-speed lamination technology independently developed, and achieved a subversive breakthrough in lamination efficiency, reaching 0.125 seconds per piece, which is more than 200% higher than the second-generation efficiency.
This will lead the power battery industry to accelerate its entry into the lamination battery generation. In this article, we will mainly introduce the top 5 stacking battery companies in the world.
Stacking battery has significant performance advantages
The data shows that the value of the mid section equipment accounts for about 35% of the lithium battery equipment, of which the winding/stacking machine is the core of the mid section equipment, accounting for about 70%. Compared with coiled battery, stacking battery has significant performance advantages:
● Higher energy density
● More stable internal structure
● Higher security
● Better magnification performance
● Longer cycle life
The lamination process can effectively avoid the pole core defects such as powder drop and gap caused by the bending of pole piece and diaphragm in the winding process;
At the same time, the magnification performance of the stacking battery is better than that of the ordinary structure, the middle ear structure and the multipole ear structure of the winding process.
From the application of battery plants, take BYD and SVOLT for example, the application of lamination technology has gradually matured, and the production efficiency has been improved rapidly. In some cases, the efficiency is super far winding.
It is expected that the laminating process in the square battery will be used on a large scale in the future. By 2027, the battery capacity using the laminating equipment will reach 845GWh, and the corresponding equipment space of the laminating machine will be about 25.3 billion RMB.
